Application filed June 20,

My invention relates to securing means for demountable ofiice partitions, and more particularly to ceiling locks for securing such partitions in position. I

The general object of the invention is to provide an improved ceiling lock Wl'llClrVYlll securely hold an entire partition in positlon and most effectively prevent sidewise dlsplacement of the partition.

A more particular object is to provide a quick detachable partition ceiling lock of the character stated which is simple in con struction, inexpensive to manufacture and highly eificient in operation.

The invention is illustrated in the annexed drawing which forms a part of th1s specification and in which,

Other objects and advantages will appear hereinafter and while I show herewith and will described a preferred form of construction, I desire it to be understood that I do not confine my invention to such preferred form but that various changes and adapta tions may be made therein without departing from the spirit of my invention as hereinafter claimed.

Fig. 1 is a fragmentary side elevation of a demountable oifice partition embodying my invention.

Fig. 2 is a transverse vertical section of the partition shown in Fig. 1 taken on line 22.

Fig. 3 is an enlarged fragmentary side elevation of the partition shown in Figs. 1 and 2 with a portion of the pilaster cap removed to illustrate my ceiling lock.

Fig. 4 is a transverse vertical section of Fig. 3 taken on line l4: of Fig. 3.

Fig. 5 is a view similar to Fig. 3, except that the pilaster and its cap are removed to illustrate my ceiling lock and the lock is shown in section.

1928. Serial No. 286,816.

Corresponding parts are designated by the same reference characters in all the figures.

In the drawing is illustrated a conventional demountable ofiice partition including a base 1, lower panel sections 1 2, lower pilasters 3 between said panel sections, a sill 4i resting upon the pilasters 3 and the lower panel sections 2, lower coping 5resting upon the sill 4, upper panel sections 6 and upper pilasters 7,1'estingupon said lower coping, and ceiling coping 8 resting upon the top of upper panel sections 6 and upper pilasters 7, the members of the pilasters 3 and 7 being detachably secured together by any suitable locking means 9. A strip of soft wood 10 is placed againstthe ceiling directly above the upper panelsections 6 and within the coping 8.

My ceiling lock includes a lower base member 11 and an upper engaging member 12. The base member 11 comprises a base plate 13 provided with an opening 14 near one end thereof, and a threaded stud 15 upstanding from the center of said plate. The engaging member 12 comprises a plate 16 provided with a central opening 17 and having its ends 18 bent upwardly with the upper edges of said ends serrated, forming prongs 19. The plate 16 is bowed downwardly slightly from end to end for the, purpose hereinafter described. A base member 11 of each lock is secured'to the top of each panel section 6 at one upper corner thereof by means of a screw 20 driven through the. opening 14 in the base plate 13 of the memher so that one half of the base plate is secured to the top of a panel section while the other. half of the base plate extends over thetop of the adjoining panelsection (Figs.

3 and 5). A nut 21 screws on the threaded stud 15 and the upper engaging member 12 is placed above the base member 11 with the stud 15 extending through the opening 17 in the plate 16 of said member and with said plate resting upon the nut 21 on the stud 15.

Upon turning the nut 21 in one direction, 10.

the nut engages the under side of the member plate 16 and forces, the member up sothat the end prongs 19 of the member engage the under side of the ceiling strip 10 firmly against the ceiling, thus securely clamping the partition between the floor and the ceiling and most effectively preventing displacement of the partition. In tightening firmly than otherwise. The breadth of plate 16 is considerably greater than its thickness and its length is considerably greater than its breadth, hence it is adapted to perform the function just recited.

Caps 22 fit on the upper ends of the pilasters to enclose the ceiling locks and for ornamental purposes. Each cap comprises a pair of members 23 and each of said members is formed with a body portion 24, a pair oi external end flanges 25 and a lower external depending flange 26. The ceiling coping 8 is cut at 27 and 28 to receive the upper end of the pilasters 7 and the body portions 24: of the members 23 of the pilaster caps 22 on both sides of the partition, the end flanges 25 and lower flange 26 oteach cap member fitting against the outside of the coping 8 and the lower edge of the lower flange 26 fitting over the upper edge of a pilaster. The members 23 of each cap 22 are secured together in position by a pair of dowels 29 which are first secured at one end in the body portion 24 of one of said members and their other ends then fitted in sockets 30 in the body portion of the other member and glued therein, the dowels extending under the ceiling strip 10 and through the engaging member 12 of one of the ceiling locks.

I claim as my invention:

1. In a demountable partition, a ceiling strip, a ceiling lock comprising a base member and a clan'iping member, each of said members consisting of elongated plates, means for securing an end portion of said base member on the upper edge of one of the panel sections so that the remaining portion of said member will rest upon the upper edge of an adjoining panel section, saidbase member being formed with an upstanding threaded stud located in spaced relation to its ends, said clamping member being provided with an opening to receive said stud,

the ends of said clamping member being bent upwardly for engaging said ceiling strip, and a nut on said threaded stud for en gaging said clamping member to force the ends of said clamping member against said strip for clamping the partition in position.

2. In a demountable partition, a ceiling strip, a ceiling lock comprising an elongated base member and a clamping member, means for mounting said base member on the top of two adjoining panel sections of the partition, said base member being an elongated plate adapted to overlie portions of adjacent panel sections, prongs on said clamping member, and means on said base member for urging said engaging member upwards so that said prongs will engage said ceiling strip. 3. In a demountable partition, a ceiling strip, a ceiling lock comprising a base memher and a clamping member, means for mounting said base member on the tops of two adjoining panel sections of the partition, said base member being formed with an upstanding threaded stud, said clamping member having a length considerably greater than its other dimensions being bowed. downwardly and provided with a centrally disposed opening to receive said stud, the ends of the clamping member being bent upwardly, and a nut on said threaded stud for engaging the under side of said clamping member for clamping the ends of said member into said ceiling strip, the pressure of said nut against said clamping member tending to straighten out said member and to cause its end portions to be directed more squarely against said ceiling strip.

4. As a new article of manufacture, a ceiling lock comprising a base plate having thereon an upstanding threaded stud, a nut adapted to screw on to said stud, a clamping strip having a. central aperture adapted to fit loosely over said stud, the diameter of said aperture being less than the diameter of said nut, said strip bowed in the direction of its length and having its end portions each bent toward one face thereof and provided with prongs.
